Abstract
System and apparatus for treating data derived in serial pulse fashion from a source such as a meter. Data words are recorded upon a magnetic bubble memory which is portable and which includes real time and identification data in addition to pulse source data. The portable storage device incorporating the magnetic bubble memory is inserted into reader apparatus for transmission by telecommunication to a translator station which may be located remotely from the reader station. Cyclical redundancy check verification of the transmission is made between the stations to assure proper transmission. Further, the translation station carries out data verification checks. Erase apparatus is provided in the vicinity of the reader apparatus to carry out a memory check for the magnetic bubble memory and an erasure thereof through the insertion of zeroes therewithin.
